Abstract
FH40 ship-building steels with Ce, Zr, Ce–Zr compound treatment were melted in medium frequency vacuum induction furnace. The characteristics such as particle size distribution, average particle size, total amount, and chemical composition of FH40 ship-building steels were investigated by OM and SEM-EDS methods. The results showed after Ce, Zr, Ce–Zr compound treatment, the average particle size decreased from 2.752 to 2.567 μm, the microstructures of experimental steels were refined remarkably, and inclusions distributed more uniformly, while the total amount of inclusions increased from 213.5/mm2 to 672.8/mm2. A1–O in the experimental steel containing 0.0053%Ce and 0.0055%Zr could be transformed into Ce–Zr–O being 33.6%. The inclusions except Al–O can induce the growth of IAF nucleation. Further analysis showed that the morphology of inclusions was affected by the amount of alloying agent addition, the misfit, and particle interfacial energy.
